Hiccup decides to befriend the dragon, which he names Toothless, and eventually fashions an artificial tail fin and control harness.
He is given a book by Gobber that contains much knowledge of the different species of dragon that assail the village, and he quickly finds through his own interactions with the dragons that the information within the book is wrong.
While helping Toothless fly again, Hiccup gains an extensive appreciation of dragons.
Hiccup and the others arrive, and, while he goes to free Toothless, the others try to distract the Red Death.
He quickly overpowers the Monstrous Nightmare, the Vikings sent to capture him, and finally Stoick.
However, Stoick's spirits are lifted when Gobber and others begin congratulating him on Hiccup's rise as a formidable warrior.
With this knowledge, Hiccup is able to progress in dragon combat training to the amazement of his classmates and the jealousy of Astrid, who becomes strongly suspicious.
